Blm leylines button bloat

[Pyitoechito]

Ability's are off-gcd and don't use the spell queue at all (they simply fail when you are in animation, macroed or not).
So dunno what you are talking about.

There is indeed a queue for all skills, on or off the GCD. If you click on Ley Lines when something like Blizzard IV is about to finish casting, Ley Lines will be queued and activate at the next available opportunity. If you put Ley Lines in a macro, then you have to wait for the animation lock of Blizzard IV to finish completely before activating the macro will have any effect.
